This invention relates'to doors'wfor grain .nears and particnla'rl` tonovel means whereby a "door maybe eld1 in the opening by means which arereadily detachable to permit the door sections to swing outwardly totree thel grain so that notwithstanding the pressure oie the grain fromwithin, the door may be manipulated to open it while at the same timethe said door will withstand unusual pressure romvwithnin, without..liabilo opening or being displaced.

'still further object ot' this invention is te produce a door 'for agrain car having prevision for supporting closure strips or at least,the bottom of a series of closure strips to provide a view,

4 tion wherein above the door so that` by use of the door and strips,the opening of a box car may be closed by means which are comparativelyinexpensive and which will prove a saving of lumber or materials usuallyemployed ttor this purpose.

still further object of this invention is door comprising separablesections adapted to be anchored to the door means for holding theseparable sections together and guarding the i prevent the ``With thelforegoing and other objects in the invention consists in the details etconstruction and'in the arrangement and combination of parts to behereinafter more 'nliy. set forth and claimed.

- Fig. 3 illustrates a. view in elevation of the the door.

' The door in the resent embodiment of the invention comprises a member8 and a member '9 preferably constructed of lumber, each `of saidmembers being pro-vided with vertically disposed plates such as 10 onits inner surface at the outer end. Each of said plates is secured to amember by fastenings 11 such as screws or nails, and each of the saidplates and members has apertures 12 for the passage of securing devices13 such as nails, it being the purpose of the inventors that the outerends of the members shall be secured to the 'car trame by nails whichwill serve to retain them in place, it. being the purpose also of theinventors that the nails shall be Withdrawn as the door sections areforced outwardly in the center, thus making is possible to employmembers Which are nailed to the frame without liability of injuring themembers owing to the fact that. the plates 1() serve asjprotections toprevent splitting or other damage to the said members so that it ispossible to use doors again and again when they are construct-ed inaccordance with this invention.

The inner surfaces of the members 'near their inner ends are providedwith plates 14 which are in the nature of Wear plates to receivefastenings such as bolts 15 and 16, -the former of which have theirouter ends terminating in eyes 17 to receive the pins 18 for holding themembers in assembled relation as will presently appear. The fastenings16 retain the face -plate 19 in place on the member 9 so that the member9 car-v ries the said face plate, and the saidface plate extends acrossthe joint 20- between the members 8 and 9 serving to seal the jointlation, and the said face plate is therefore locked in engagement withthe member 8 as fully shown in Fig. l.

An important element of this invention is found in the fact that theface plate 19 extends above the upper edges of the members 8 and 9 andforms a seat for the lowermoet strip 7 which strip rest-s on the uppersurfaces of the members 8 and 9 and against the rear surface of the faceplate in such a manner that the members 8 and 9 are free to swingoutwardly butare braced against inward movement by reason of engagementof the face plate with the outer surface of the lowermost strip 7, andthe strip 7 is prevented from vbulging in the center by reason of itsContact with the face plate.

rlhe plate 19 has a wear plate Q2 on its outer Surface which is engagedby the pins 18 so that notwithstanding there would be relative movementof the face plate with relation to the bolt having thel eye 17 the pinswould not damage the said face plate.

Ne claim:

In a car door, door members separable from one another, tlie saiddoormembers' having metallic fa'cings on their inner Sides at the outer ends`apertured to receive liastenings entering a door frame of a box car, aface plate adapted to lap the oint between the said door members andproject thereabove to form an abut-nient for a lowermost closure memberabove the door, and means for securing the face plate to the doormembers on opposite sides of the joint between said door members. l
